DUMP-CAR.

Specification of Letters Patent.

Patented Dec. 8, 1908.

Application led .I une 24, 1908. Serial No. 440,108.

To all whom it may concern:

Be it known that I', SAMSON l). WRIGHT, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Dump-Cars, of which thefollowing is a specification.

This invention relates to dump cars 'or conveyers and particularly tothat type of.

V contents.

In carrying out my invention I support the car body, the lower portionof which is preferably rounded or semi-cylindrical, at its ends onsuitable uprights or standards carried by the frame and also providerollei` supports for the car body intermediate its ends, whereby theweight is distributed and the, turning or rolling is facilitated. Theroller bearings referred to are preferably carried by the frame on crosssills and there may be as many series of rollers as is desired, thenumber depending generally upon the length and size of the car. 'The carbody is provided with ways or tracks extending around the saine4 andadapted to be engaged by the rollers, said ways being preferably in theforni ol' channels secured to and extending around the lower part of theear body and the latter braced on the interior in the planes by therollers by transverse walls or partitions which )are preferably providedwith perforations so that when the material contains liquid, saidperforations will permit the liquid-to seek its level.

The invention also relates in other aspects, to means for taking care ofthe end thrust of the car body and means whereby the weight of the cnrbody and its contents is wholly or partially removed from the rollerbearings when the car body is in its normal position.

'Bly invention may still further be briefly sunlnnirized as consistingin certain novel details of construction and combiinition andarrangement of parts `which will bedescribed in the specification andset forth in the appended claims. p

For a better understanding of my invention reference is had to theaccompanying drawings in which Figure 1'isal side elevation of a portionof the car equipped with my invention, parts being broken away for thesake of clearness g Fig. 2 is a partial end elevation and transversesection of the same 5 and Fig. 3 is an enlarged partial transversesection substantially along the line 3 3 of Fig. 1 looking in thedirection indicated by the arrows.

In the figures of the drawing, 10 represents the supporting frameprovided with suitable car trucks 1 1 which are preferably of a standardtype, and 12 the car body,'which as will be explained is so supportedand mounted that it may be turned orrolled on its sup ports preferablythrough an arc of 9() degrees so that the contents may be dumped orremoved from the interior. The car frame 10 is preferably built up ofrolled plates and angle sections and consists of two longitudinallyextending side girders 13 and cross sills, which will be explainedlater. The

frames are provided at the ends with upwardly projecting supportingframes or.

standards 14, which form the main supports for the -car body, saidstandards being referably built up of plates and angles and aving a flatupper flange or surface 15 upon which bearing members of the car bodyrest and are adapted to roll in the dumping process. Locatedintermediate the ends of the frame are cross sills 16 each of whichconsists in this case of two spaced channel members 17, with the backsadjacent each other, and plates 18 which are secured to the backs of thechannel members and which carry a series of roller lbearings 10 forsupporting the car body intermediate its ends in the turning or rollingoperation. The number of these sills and series of rollers will dependlargely upon the size and capacity of the car, in Fig. 1 of the drawingtwo series only being shown, a little less than hall' of the car beingshowr. on said figure. 'lhe roller bearings l0 are mounted on studs 2t),the ends of which are received in suitable recesses or bearings 21, ofsupportii'ig members 'lextend'ing longitudinally of the sill and securedto the sides ofthe plates 1 8 of the sill by bolts or rivets 23,

The car body 12 is built up of rolled plates angl as here shown has arounded or substan- A tending in this case upwardly a short distancebeyond the curved or rounded portion as shown at 25. The body isprovided with hinged lids or covers 26 which may be locked in positionby clamps 27,. The ends ofthe car body are each provided with a bearingorsupporting flange 2S preferably of cast metal, which flange rests uponthe top 15 of the corresponding standard 14; at the end of the frame.This flange, as is shown, is substantially U-shaped, thev lower partbeing semicircular, the circular portion being concentric with therounded portion of the car body. These flanges 2 8 are adapted to rollupon the upper surfaces of the standards and are each provided with aseries of lu s or teeth 29 which engage corresponding oles or openingsin the top of the standard so that when the'car body is being turned inthe dumping process, they act somewhat similar to a gear and rack. Thecar body is provided with Ways for the roller bearings, said waysconsisting in this case of channels 30, which are secured to the Wallsof the car body and -which are rounded or curved in the arc of a circleconcentric with the rounded portion of the supporting flanges at theends of the car body and as the car body is also rounded, theways followclosely vthe contour of the rounded portion thereof. These channels 30areflocated opposite allthe series of rollers Two of these members 34are located over and engage the rollers during the turning or rollingoperation.

I provide on the interior of the car body iri the plane of each seriesof rollers, means for bracing the car body, said means consisting inthis case of transverse plates or partitions 31 which are secured to thecar body by angles 32 located on each side of the plates and followingthe contour of the car body. These plates are preferably provided with anumber of perforations 33 so that in case the material carried, such asgarbage for which this car is especially adapted, contains liquid, thelatter may seek its level regardless in which section of the car thematerial is thrown. It will be seen that with this danger of anymaterial carried by the car becoming entangled or caught as would be thecase if other forms such as lattice work were employed.

Secured to the bottom of the car body are a number of plates or castings34 each having a central, rounded lug or enlargement 35.

each cross sill 16 in a position such that when the car body is in itsnormal upright position the lu or enlargements engage the llanges'of thechannels of the cross sills and thus relieve the rollers directly underthe centery of the Acar body wholly or partially of the Weight of thecar body and itsL contents. The lugs or enlargements are so shapedhowever that as soon as' the car body is turned from its normal uprightdposition it rolls, so to speak, off said lugs an engages the rollervbearings.

In order that the supporting flanges at the ends ofthe car body may berelieved of the end thrust, vwhich may be considerable in a I provide onthe bottom of the car body on each side of the sills 16, short angles 36having llanges 37 which extend downward below the sills and adjacent theflangesof the channels 17 thereof, so that in case the car body isshifted longitudinally the flanges of the angles en age the channels.For this same purpose provide o n each-end standard 14 ad'acent the bodyof thecar when in its normal position a plate 438 having an enlar ementadapted to be engaged by. .the car bouyv When the latter is shiftedlongitudina y. y

I do not desire to be confined to the exact details shown-but aim in myclaims to cover all changes o1' modifications which do not involve adeparture from thespirit and scope of my invention.

Furthermore I do not desire my improveplying to other forms ofconveyingvehicles,
